Police spokesman Ruwan Gunasekera declined to give a breakdown of those killed and wounded at each of the three churches and four hotels hit on Sunday, attacks that marked the most significant violence since a bloody civil war ended 10 years ago.

A government source said President Maithripala Sirisena, who was abroad when the attacks happened, had called a meeting of the National Security Council early on Monday. Prime Minister Ranil Wickremesinghe would attend the meeting, the source said.
